Definitions

  • the present invention relates to a novel class of substituted phenylpiperazinyl,-piperidinyl and -tetrahydropyridinyl derivatives having affinity for dopamine D4 receptors.
  • the compounds are useful in the treatment of certain psychiatric and neurologic disorders, including psychosis.
  • Dopamine D 4 receptors belong to the dopamine D 2 subfamily of receptors, which is considered to be responsible for the antipsychotic effects of neuroleptics.
  • the side effects of neuroleptic drugs, which primarily exert their effect via antagonism of D 2 receptors, are known to be due to D 2 receptor antagonism in the striatal regions of the brain.
  • dopamine D 4 receptors are primarily located in areas of the brain other than striatum, suggesting that antagonists of the dopamine D 4 receptor will be devoid of extrapyramidal side effects. This is illustrated by the antipsychotic clozapine, which exerts higher affinity for D 4 than D 2 receptors, and is lacking extrapyramidal side effects (Van Tol et aI. Nature 1991 , 350 , 610; Hadley Medicinal Research Reviews 1996 , 16 , 507-526 and Sanner Exp. Opin. Ther. Patents 1998, 8 , 383-393).
  • D 4 ligands which were postulated to be selective D 4 receptor antagonists (L-745,879 and U-101958) have been shown to posses antipsychotic potential (Mansbach et al. Psychopharmacology 1998 , 135 , 194-200).
  • these compounds are partial D 4 receptor agonists in various in vitro efficacy assays (Gazi et al. Br. J. Pharmacol. 1998 , 124 , 889-896 and Gazi et al. Br. J. Pharmacol . 1999, 128 , 613-620).
  • clozapine which is an effective antipsychotic, is a silent antagonist (Gazi et al. Br. J. Pharmacol . 1999 , 128 , 613-620).
  • D 4 ligands which are partial D 4 receptor agonists or antagonists, may have beneficial effects against psychoses.
  • Dopamine D 4 antagonists may also be useful for the treatment of cognitive deficits (Jentsch et al. Psychopharmacology 1999, 142, 78-84 .
  • dopamine D 4 antagonists may be useful to reduce dyskinesia occurring as a result of the treatment of Parkinson's disease with L-dopa (Tahar et al. Eur. J. Pharmacol . 2000, 399 , 183-186).
  • Dopamine D 3 receptors also belong to the dopamine D 2 subfamily of receptors, and they are preferentially located in limbic regions of the brain (Sokoloff et al. Nature , 1990, 347 , 146-151), such as the nucleus accumbens, where dopamine receptor blockade has been associated with antipsychotic activity (Willner Int. Clinical Psychopharmacology 1997, 12 , 297-308). Furthermore, an elevation of the level of D 3 receptors in the limbic part of schizophrenic brains has been reported (Gurevich et al. Arch. Gen. Psychiatry 1997, 54 , 225-32).
  • D 3 receptor antagonists may offer the potential for an effective antipsychotic therapy, free of the extrapyramidal side effects of the classical antipsychotic drugs, which primarily exert their effect by blockade of D 2 receptors (Shafer et al. Psychopharmacology 1998, 135, 1-16; Schwartz et al. Brain Research Reviews 2000 , 31 , 277-287).
  • D 3 receptor blockade results in a slight stimulation in the prefrontal cortex (Merchant et al. Cerebral Cortex 1996 , 6 , 561-570), which could be beneficial against negative symptoms and cognitive deficits associated with schizophrenia.
  • dopamine D 3 antagonists can reverse D 2 antagonist-induced EPS (Millan et al. Eur. J. Pharmacol . 1997 , 321 , R7-R9) and do not cause changes in prolactin (Reavill et al. J. Pharmacol. Exp. Ther . 2000, 294 , 1154-1165). Consequently, D 3 antagonistic properties of an antipsychotic drug could reduce the negative symptoms and cognitive deficits and result in an improved side effect profile with respect to EPS and hormonal changes.
  • Dopamine D 3 agonists have also been considered relevant in the treatment of schizophrenia (Wustow et al. Current Pharmaceutical Design 1997 , 3 , 391-404).
  • a number of dopamine D 4 ligands which can be described by the general formula wherein Het is 3-pyrrolo[2,3-b]pyridinyl, 2-benzimidazolyl, 3-indazolyl, 2-indolyl, 3-benzofuranyl, imidazo[1,2-a]pyridinyl, 3-furo[2,3-b]pyridinyl and 3-benzofuranyl and Ar is optionally substituted phenyl, have been described in WO 9420497, WO 9422839, WO 9421630, WO 9424104, WO 9909025, WO 9529911, WO 9625414, US 5700802 and J. Med. Chem . 1996 , 39(19) , 1941-2.
  • WO 9604250 relates to certain 1-(3-piperazinopropyl or 3-piperidinopropyl)benzimidazoles having dopaminergic activity.
  • dopamine D 3 antagonistic properties of an antipsychotic drug may reduce the negative symptoms and cognitive deficits of schizophrenia and result in an improved side effect profile.

  • the compounds of the invention have been found to show affinity for the dopamine D 4 receptor and many of the compounds also have alfinity for the dopamine D 3 receptor.
  • the compounds of the invention are therefore considered useful for the treatment of psychoses including the positive and negative symptoms of schizophrenia.

  • affective disorders such as generalised anxiety disorder, panic disorder, obsessive compulsive disorder, depression and aggression.
